ang alam ko pag sony nasa 90V pataas ang B+ kung hindi pa nag o oscilate ang flyback. pero pag gumana ang flyback saka sya aakyat ang B+ sa 115Volt.

pero yung sayo parang ang baba ng B+ pag walang OSC.
try mo kaya isaksak muna sa 110V tapos check ang B+ kung same pag naka 230V ang input.
kung hindi parehas, concentrate ka sa PS section.
